the measurement of the ∠R will be 101 degrees.

A quadrilateral with the opposing sides parallel is called a parallelogram (and therefore opposite angles equal). A parallelogram with all right angles is known as a rectangle, while a quadrilateral with equal sides is known as a rhombus.

Given TPRS is a parallelogram. in that ∠T = (4x +1) and ∠S = (3x +4)°

Since in a parallelogram, opposite angles are equal Thus,

∠P = ∠S = 3x + 4

∠R = ∠T = 4x +1

Since we know the sum of all angles of a quadrilateral is 360°

3x +4 + 4x +1 + 3x +4 + 4x +1 = 360

14x + 10 = 360

14x = 350

x = 350/14

x = 25

Thus,

∠R = 4x +1

∠R = 4 *25 + 1

∠R = 101°

therefore, the measurement of the ∠R will be 101 degrees.

The cardinal number of G = 0 for the given set G = {x|x ∈ N and x is a negative}.

A set is defined as a group of objects in mathematics. Set names and symbols begin with a capital letter. According to set theory, a set's constituent parts can be included in anything.

The set is given in the question, as follows:

G = {x|x ∈ N and x is a negative}

We have to determine the cardinal number of set G = {x|x ∈ N and x is a negative}

Cardinal numbers, also known as Cardinals of a Set, are the numbers used to count the number of elements in a Set.

Simply expressed, the cardinal number of a set equals the number of items in a set.

Let A = {a, b, c, d}  be a set then Cardinal number of A is 4

Given G = {x|x ∈ N and x is a negative}

Here, x belongs to N, and a negative number

Since Natural Number (N) = 1, 2, 3, 4 ...

There is no negative value that corresponds to N.

Thus, G = { } or G is an empty set.

Hence, the cardinal number of G = 0

The required  sum of the first n odd numbers is equal to n².

The first few odd numbers are 1, 3, 5, 7, 9, 11, and so on. When we add up the first few of these numbers, we get the following sums:

1 = 1

1 + 3 = 4

1 + 3 + 5 = 9

1 + 3 + 5 + 7 = 16

1 + 3 + 5 + 7 + 9 = 25

We can see that the nth odd number is equal to 2n - 1. And the sum of the first n odd numbers is equal to n². This can be verified geometrically by considering a square with sides of length n.

The sum of the first n odd numbers can be thought of as the sum of the diagonal elements of the square, which forms a square of length n.

Thus, the sum of the first n odd numbers is equal to n².

Interest earned = 9/100 * $580 = $52.20

Second year

Balance + Interest = $580 + $52.20

Total balance = $632.20   (Note: Total balance = Balance + Interest )

Interest earned = 9/100 *  $632.20 = $56.90

The requried measure of the angle ∠2 = ∠5 = ∠15 = 125, ∠11 = 88, ∠3 = ∠9 = ∠13 =  102°, ∠4 = ∠14 = 78°, ∠7 = 37, ∠8 = 41, ∠1 = ∠6 = ∠10 = 16 = 55°.

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

here,
from figure,
∠2 = ∠5 = ∠11 + ∠12 = ∠15 = 125

From the above expression,
∠2 = ∠11 + 37°
125 - 37 = ∠11
∠11 = 88°

Similarly.
∠3 = ∠9 = ∠13 = ∠18 = 102°
∠4 = ∠7+∠8 = ∠14 = ∠17= 78°
∠1 = ∠6 = ∠10 = 16 = 55°

The statement is true. Matrix multiplication is not commutative, so the product of the transposes of the matrices must be applied in the same order as the initial product, not in a reverse order.

The statement that the transpose of a product of matrices equals the product of their transposes in the same order is true. Matrix multiplication is not commutative, which means that the order in which the matrices are multiplied matters. That is, for two matrices A and B, AB does not necessarily equal BA. Thus, when taking the transpose of a product of matrices, the order in which the transposes of the matrices are multiplied must be the same as the order in which the original matrices were multiplied. Otherwise, the result will not be the same. For example, if two matrices A and B are multiplied to give AB, the transpose of AB will be (AB)^T = B^T A^T, not A^T B^T. This is why the product of the transposes must be applied in the same order as the initial product.

Answer:

C(t) = 0.50 * t + 2.50

Step-by-step explanation:

The function C(t) to represent the cost of a taxicab ride can be written as:

C(t) = 2.50 + 0.50 * t

where t is the distance traveled in tenths of a mile.

The slope of the graph of this function is 0.50, which represents the cost per tenth of a mile.

The y-intercept of the graph of this function is 2.50, which represents the fixed fee that must be paid regardless of the distance traveled.

So, the equation of the graph of this function is:

C(t) = 0.50 * t + 2.50

The equation 15 - x = 7 models the scenario because it represents the decrease in the number of cats that the zoo now nurses. It can be read as "15 (the number of cats originally) minus x (the number of cats moved) equals 7 (the number of cats the zoo now nurses)".

Calculate the slope of segment AB and CD.

The slope is given as:

m = (y2 - y1) / (x2 - x1)

For AB:

m = (9 - 0) / (0 + 2) = 9/2

For CD:

The function that describes the sequence maps each index or position to its corresponding value.

A sequence space is a vector space that contains endless sequences of real or complex numbers. It is used in functional analysis and related mathematical fields. It is, in essence, a function space whose constituents are functions from the natural numbers to the field K of real or complex numbers.

The notation f(2) = 4 indicates that a term in a sequence defined by a function has a value of 4 when the term's index or position is 2.

Because sequences are a collection of ordered pairs with the first element being the index or position of the term and the second being the term's value, they can be characterised as functions. The function that represents the series maps each index or location to its associated value, and these ordered pairs can be seen as points on a coordinate plane.

The angle that is adjacent to the angle CED is the angle DEA.

When two angles have a similar vertex and side, they are referred to as neighbouring angles. The vertex of an angle is the point at which the rays that make up its sides come to an end. When adjacent angles have a same vertex and side, they can be a complimentary angle or supplemental angle.

An adjacent angle is complementary to another if the total of its adjacent angles is 90 degrees.

When the total of two adjacent angles is 180 degrees, they are supplementary to one another.

Two angles are said to be adjacent angles when they share a common vertex.
